How the Heart and Lungs Actually Work (and How They Test You)

In Episode 14 of the Jack Westin Podcast, Mike and Molly break down everything you need to know about fluid dynamics within the respiratory and cardiovascular systems for the MCAT.You'll learn how real-world physics—like Boyle’s Law and pressure gradients—directly impact lung ventilation, gas exchange, and blood circulation across the body.

✅ Understand the "why" behind O₂ intake and CO₂ removal (and how biochemistry plays a role)

✅ Master the mechanics of inspiration and expiration (and why breathing isn't just about air!)

✅ Learn how ventilators work and apply these concepts clinically

✅ Break down heart flow circuitry (Right Atrium → Lungs → Left Atrium → Body) without memorizing

✅ Debunk common myths about blood pressure in capillaries and veins

💡 PLUS: Real clinical connections to motivate your studying—including how abdominal aortic aneurysms (AAA) develop, and why vein valves are critical for blood return.

This is the kind of critical thinking and systems-level understanding the MCAT demands—and we’ll show you how to master it.
